it further object of my invention resides in effectively bracing a roadway surface scraping and crowning apparatus capable of adjustment to roadways of various widths. and in maintaining the effective,

braced condition in any one of the adjusted positions of the apparatus.

Other objects and advantages of my invention will become more apparent as the following description of one embodiment thereof progresses, reference being made to the accompanying drawings. in which like reference characters are employed to designate like parts throughout the same.

including the longitudinals 1 in a desired position above the surface of the roadway.

The frame also includes lateral members comprising telescopic sections 5 and (i, and T and 8, likewise preferably formed of standard channel iron or beam sections. The sections 5 are adjustably supported at their outer ends upon the forward ends of the longitudinals, which are apertured at spaced intervals, as at 9, to receive the pins or bolts 10 passing through the opening in the ends of respective sections The sections 6, adjustably secured-to the sections 5 by means of the bolts 11 which may be inserted in any of the registering series of openings 12 formed in the sections 5 and 6, and secured in place by the nuts 13.

The telescopic lateral sections 7 and 8 are also preferably formed of standard channel iron or beam sections, the outer ends of which are rigidly secured to and supported upon the longitudinal 1 near their rearward extremities. as at 1t. These lateral telescopic sections 7 and 8 are likewise adjustable laterally of the frame. the said sections being apertured at spaced intervals as at 15, so that the sections may be slid one upon the other to the required adjustment corresponding to the adjustment of the sections 5 and 6. Bolts 16 are then passed through certain of the registering openings and secured in place bythe nuts 17.

It will be seen therefore that T have pro vided a frame for straddling a roadway, which is capable of lateral and longitudinal adjustment to roadways of predetermined width,

T have also provided means for securely diagonally bracing the frame in any of those This means includei's'the forwardly converging diagonal channels or beams 18. shown as pivotally connected and supported at their forward ends to the channel 6 by means of a single pin 19. and piv- 'otally connected at their rearward ends to the respective telescopic channel sections 7 by means of the pins 20 and the supporting To the rearward ends of the diagonals are secured suitable bearing plates 22 and QKhaving aligned openings therethrough for the passage-of the pin 20. The forward ends of the diagonals are provided with-bearing plates 2t and 25 having aligned openings .for receiving the pin 19.

It will be noted, in referring more parother.

' through openings in the laterals 7.

ticularly to Fig. 4, that the substantially vertical flat walls of the diagonals 18 are disposed outwardly toward the flat sides of the channels 2. Adjustably secured to the vertical flat walls of the scraper channels 18 are scraper plates 26 having elongated vertical slots 27 formed. therein for receiving the projecting ends of the bolts 28 carried by the scraper channels. In thismanner the scraper plates may be adjusted vertically on the channels 18 to a scraping level slightly below the material engaging edges of the crowning plates 29. It will be observed that the scraping plates 26 are adjustable independently of one another and of the crowning plates carried by the laterals 7, providing a suitable range of adjustment for all the road surface members. Thus the diagonals not only effectively brace the frame in any of its adjustments, but also constitute forwardly converging scraper members for engagement with the material on the road surface as the frame ismoved therealong to force the excess material on the roadway surface outwardly toward the vertical edging faces of the channels 2.

I have provided means for crowning the surface of the roadway which includes vertically adjustable crowning plates 29 adjustably secured to the laterals 7, as shown more clearly in Figs. 3 and 4. These plates are slotted vertically at spaced intervals as at 30, for receiving the project-ing ends of supporting pins or bolts 31, which project The road surface engaging edge 32 of each of the plates 29 is inclined slightly upwardly toward the longitudinal axis of the frame to produce a corresponding inclined contour or crown to the road surface as the frame is moved therealong. i

It will be noted that the crowning plates normally extend slightly below the road surface engaging edges of the scraper plates on the diagonals 18 and are disposed behind these diagonals so that in moving the frame forward along the roadway the excess material is scraped from the roadway toward the longitudinals before the crowning plates engage the scraped surface.

In use the operation of my invention illustrated in the accompanying drawings, may be described as follows: 7.

Assuming that the apparatus is to be set up for scraping, crowning and for leveling a roadway surface of predetermined width, the longitudinals including the beams 1 and 2 and the filler blocks 4 are first set up along the opposite sides of the roadway the flat vertical walls of the beams 2 facing one an- The lateral section 8 is secured in telescopic relation to the laterals 7 and secured thereto in the desired adjusted position by means of the bolts 16'. The diagonals 18 are pivotally connected at their rear ends to the laterals 7 and converge forwardly where their forward ends are secured together and suspended from the lateral section 6 by means of the pin 19. In completing the assembly ofthe apparatus, the laterals 5 are adjusted and secured at their outer ends to the longitudinals 1 and are secured to the lateral section 6 by means of bolts 11 passing through the registering openings. The crowning plates 29 may be secured to the respective laterals 7 and adjusted to the desired elevation with respect to the road surface. In a like manner the scraper plates 26 are secured to the scraper channels 18 at the desired elevation.

It will be seen that my invention provides for a very sturdy, yet simple frame and bracing structure, the frame being capable of adjustment to roadways of predetermined width, and being securely braced in any of these adjustments.

It will also be seen that my invention provides for economical construction, since the frame and bracing members may be formed of standardized market materials such as standard channel iron or beam sections.

Various changes in the details of construction may be made without departing from the spirit of my invention or the scope of the appended claims.

I claim:

1. An apparatus of the class described including a substantially rectangular road straddling frame, comprising spaced longitudinal frame members, telescopic sectional lateral members connecting the longitudinals, the telescopic sections thereof being capable of selective adjustment one upon the other whereby the longitudinals may be spaced to straddle a roadway of predetermined width, and substantially diagonally disposed scrapers converging toward the forward end of the frame, said scrapers being pivotally secured to certain of the lateral frame sections to brace the frame in any one of its adjustments.

2. An apparatus of the class described including a substantially rectangular road straddling frame comprising spaced longitudinal frame members, telescopic sectional lateral members connecting the longitudinals, the telescopic sections thereof being capable of selective adjustment one upon the other whereby the longitudinals may be spaced to straddle a roadway of predetermined width, and substantially diagonally disposed scrapers converging toward the forward end of the frame, said scrapers being pivotally secured to certain of the lateral frame sections to brace the frame on anyone of its adjustments, and road surface crowning plates laterally suspended within the said frame. I

3. An apparatus of the class described including a substantially rectangular road straddling frame comprising spaced longitudinal frame members, telescopic sectional lateral members connecting the longitudinals, the telescopic sections thereof being capable of selective adjustment one upon the other whereby the longitudinals may be spaced to straddle a roadway of predetermined width, certain of said lateral sections being supported by the longitudinals and capable of adjustment along the same.

4.
